HEEL-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 589,501, dated September '7, 1897.

Application filed August 17, 1896. Serial No. 602,987.

To all whom it may concern:

Be it known that CHARLES W-. GLIDDEN,

deceased, late a resident of Lynn, Massachusetts, invented an Improvement in Heel-At- 5 taching Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Certain types of heels are compressed and loaded with attaching-nails before they are attached to the soles of the boot r shoe. These heels are generally of a larger and coarser kind, but not necessarily so, and it has been customary to center and hold them for attachment in a relatively deep die-holder which conformed to the shape of the compressed heel and the edge of which projected above the outsole of the boot or shoe at the end of the attaching action. This necessi- 2o tated that the boot or shoe be prepared for I the attaching operation by having the section of the sole about the heel which extends beyond the counter trimmed oif in order that the top of the heel holder or die should not come in contact therewith. This involves a manipulation which can be avoided, as will hereinafter be described, as if the heel is attached to the sole before its edge is thus trimmed the sole edge can subsequently be removed in the act of trimming the heel.

To carry the invention into effect, there is employed a heel holder or die of a peculiar shape for holding a loaded heel during its attachment to the sole of a boot or shoe, but which is so shaped that it does not come in contact with the edge of the outsole if left projecting at the heel, and there is also used in connection with such a holder devices for centering the heel end of the boot or shoe in 40 relation to the heel and its holder, which centering devices act automatically to center the shoe and also automatically to release it, and which are separated from the heel holder or die to permit of the insertion between them of the untrimmed heel end of the outsole.

The invention will now be described in con nection with the drawings, wherein- Figure 1 is a view in front elevation of a machine having the features of the invention.

(No model.)

Fig. 2 thereof, showing position of parts at the end of the downward movement of the shoe and stump. Fig. 3 is a viewin horizontal section upon the dotted line a: 00 of Fig. l and in plan of the parts below said line. Fig. 4. is a view in vertical section upon the dotted line yy of Fig; 1 and in elevation of parts in front of said line. Fig. 5 is an enlarged view, principally in verticalsection, showing the position of the shoe, heel, and various of the operative parts of the machine immediately preceding the attaching operation. Fig. 6 is a view in perspective of a loaded heel-blank, and Fig. 7 is a detail view representing the position of the parts upon the stopping of the machine.

A represents the heel holder or die. It has the relatively shallow heel-holding cavity or recess a, which is of the shape of the exterior of the heel which is to be held byit, but which does not extend at thesides or back sufliciently to prevent the untriinmed back of the outsole from closing over it in the act of jacking the shoe, (see Fig. 5,) and the front wall of which at a is cut away to prevent con- 7 5 tact of this section of the holder with the shank of thelooot or shoe when it is in its lowest position.

The holder or die is downwardly movable on the spindle a against the pressure of the spring a which restores the die and its attachments to their normal or usual elevation. Upon the upper part of the spindle a is the spanking-plate a which forms the bottom of the die or holder and upon the upper surface of which the loaded heelis placed, said plate remaining stationary while the holder or die is moved downward by the jack or stump to attach the heel to the heel end of the shoe by driving the nails through the heel and into 0 the sole thereof during said downward movement. The said spindle a may be adjusted vertically in the nut a The boot or shoe is presented to the heel held by the die or holder by means of a jack 5 or stump B at the end of an arm b,'which is pivoted at b to a vertically-movable pressureslide B, the arm being arranged to be swung is a'view in vertical central section 50-- outward to the position represented in Fig. 1 to receive the shoe and then inward to a position over the heel and its holder.

The jack or stump is in two parts, the lower part 11 being united to the upper part by a dovetail tongue, which enters a dovetail recess therein, so arranged that it may be moved laterally or from side to side of the part 5 It is also wider than said part, and the object of this construction is to permit the shoe and the lowersection of the stump to be moved laterally by the shoe-centerin g devices as the shoe and the stump are being moved into operative position. The shoe centering devices comprise the arms or side guides O O, pivoted at c respectively, to a plate 0 which is. horizontally adjustable upon the bracket 0 toward and from the jack or stump when in operative position by the adj listing-screw 0 the arms or'side guides being connected between their pivots by intermeshinggear-sectors c 0", respectively, so

that the movement of one arm or guide will cause alike movement of the other, or so that they shall separate or move uniformly. These arms extend forward from a pointback of and above the level of the top of the heelholder to a position above and upon each side thereof, and they are so shaped as to automatically center the shoe and the plate of the last or stump as they are moved into position over the holder, the counter of the shoe at its sides comingin contact therewith as the shoe and the jack or stump are being moved between them. These arms are separated from the top of the die by the space 0 sufficient in extent to receive any projection of the outs'ole. A spring a back of their pivots acts to close them and to resist with yielding pressure the inserting of the shoe between them.

There is also used for centering the shoe the back-stop D, which is in the form of a V-shaped recess in the front edge of the plate d, the plate and back-stop being above or over the side arms or guides and being secured by the studs which form the pivots of the side guides to the slide-plate 0 so that they are horizontally movable lengthwise the heelholder with the side guides. By means of slots formed in said plate in line with the studs 0 the back-stop may be made adj ustable lengthwise the side guides and inde' pendently of them.

The bracket or support 0 which holds the side guides and back-stop, is herein shown as attached to a foot-piece 10, which is supported by the heel holder or die, said foot-piece hav ing ears 6 upon each side from which extend forwardly studs 6, which enter holes formed in cars or lugs 6 upon each side of the heel holder or die, the said studs being movable horizontally in said holes to permit the footpiece and bracket or support to be moved away from the heel holder or die as the heelholder approaches the end of its downward movement, the said backward movcmentbeing given the foot-piece and bracket or sup port by means of aninclined cam or guide in the bracket 1, extended upwardly from the stand F. The bracket and foot-piece constitute supporting means for the side guides.

It will be understood that during the first part of the downward movement of the shoe and stump or jack the side guides and backstop are moved downwardly with it, the shape of the cam f being such that it does not act to withdraw the foot-piece and side guides and back-stop until the sole of the shoe has firmly seated itself upon the heel. The stand F also carries a post f to the upper end of which are secured by the set-screw f upwardlyopening V-shaped or diverging surfaces or cams f These are arranged below the rear ends f of the arms or side guides G O, which are made in a rounded form or which may have rolls attached to them and which, when the side guides are in theirhighest position, do not interferewith the opening or closing action thereof, but upon approaching the end of the downward movement of the jack or stump B and shoe the side guides are automatically opened by the contact of their ends with said inclined surfaces or cams f while they with the back-stop are also moved backward by the backward movement of ihe foot-piece and support or bracket 0 due to the action of the cam f upon the cam pin or stud w of the said foot-piece during its downward movement. At the end of this downward movement the heel-holder and bracket 0 are in their backward position, the back-stop removed from the shoe, and the side guides opened from the shoe are engaged by a latch device to be described, which holds them stationary in these positions while the jack or stump rises to its original position. This latch device comprises the spring-controlled lever G, pivoted to the stud f to swing or move horizontally su iiiciently to bring its end into a position to be engaged by the latch g on one side of the foot-piece, the outer surface of said latch and the upper edge of the lever being beveled, so that upon the contact of the latch in its downward movement with the lever the lever will be turned to one side until the hook of the latch has passed below the lever. The lever under the action of the spring moves, engages the latch, and holds said parts in their depressed and opened position. The shoe and attached heel are then readily removable from the heel-holder and from the side guides and back-stop.

It is understood that the backward and opening movements of the side guides and the backward movement of the back-stop are for the purpose of permitting the removal of a shoe having an untrimmed or projecting section of the sole at the heel end from the machine without interfering with the side guides or back-stop.

Upon the outward movement of the heeled shoe and jack or stump by or through the releasing-arm II and link h the heel-hold er, side guides, and back-stop are released and permitted to automatically resume their original position, the lower end of said releasing-arm upon its outward movement contact-ing with the short end 77/ of the lever G, thereby causing the latching end of said lever to be removed from the latch g.

There is lost motion between the link and the arm I), provided by the slot h in the link and pin h.

The operation of the machine is as follows: The loaded heel-blank is placed in the heelholder and the boot or shoe upon the jack or stump when it is in its outward position, (shown in Fig. 1,) and the jack or stump is then moved inwardly over the heel-holder and heel, as in Fig. 5, the shoe during such movement being automatically centered over the heel by the side guides and back-stop, the side guides and back-stop having, however, been first adjusted to a predetermined relation to the holder, the side guides automatically conforming to variation in width of the shoe and dividing such variation equally between them, causing the shoe and the movable section Z) of the jack or stump to be moved laterally one way or the other to conform, and leaving the untrimlned rear edge of the sole extending over the holder. (See Fig. 5.) The machine is then started and the jack or stump and shoe are moved downwardly, the shoe being held centered by the side guides and back-stop until the sole seats itself upon the heel and thereafter the driving of the nails by the continued downward movement of the jack or stump begins, and as the nails are driven the holder or bracket with its attached side guides and back-stop not only descend but are also moved backwardly away from the shoe, and the side guides are at the same time opened away from the shoe, and the cams f hold the said side guides opened, and finally the latch device engages and locks the holder or bracket down, so that the jack or stump, with its shoe having the heel attached thereto, may be lifted from between the side guides and back-stop and the jack or stump be im mediately and easily swung outwardly from over the heel-holder in order that the shoe may be removed. This outward movement of the jack or stump causes the heel-holder, side guides, and back-stop to be automatically released and they then automatically return to their original or operative position. The throw of the jack or stump is small in order that the sole may be as near the seat of the heel as practicable before the machine is started. I

The back-stop may be attached directly to or formed upon the side guides.

The side guides may have. a backward movement onlythat is, they need not always have an opening movement.

The jack or stump pivoted at Z) may be readily and quickly moved into and out of operative position, thus avoiding the use of sliding spindles having holders attached to in g instrumentalities, viz: a heel-holder to re-,

ceive and center a heel-blank, a pivoted jack or stump adapted to receive the shoe to which the heel is to be attached, and automaticallyacting, uniformly-yielding side guides having their acting ends arranged above and at opposite sides of the center of said heel-holder, said guides receiving between them the heelcovering end of the shoe to which the heel is to be attached to thus center the heel end of the sole of the shoe correctly over the heelblank, substantially as described.
